Thanks for posting the U2 video, Grav.
I suppose that it's human nature, up to a point, to be curious about things that you're not supposed to know about. For that reason the U2 has always been a source of considerable interest.
Strange to relate, but I have here a facsimile copy of the pilot's notes for the U2. A little light reading, you understand.
